Add application insights connection string support

Description:
The PR adds support for adding release annotations when the now recommended APPLICATIONINSIGHTS_CONNECTION_STRING setting is used on Azure, rather than the APPINSIGHTS_INSTRUMENTATIONKEY, for all tasks supporting this feature.

Documentation changes required:
I don't think so.

Added unit tests:
No.
I did not find tests for release annotation based on InstrumentationKey.
I had a hard time figuring how to add unit tests for the connection string use case, and tests seem to come from another zone of the code.
Happy to get guidance on the matter however.

Attached related issue:
#18796 (closed due to being stale, probably needs reopening)

Can you update the Task.json as mentioned?

Sure, I just did, and updated issue template too. Feel free to point any mistake I would have made in the process of course!

Looks good to me from the Function side of things. Thanks for the contribution.

hi @jvano, @dannysongg, @manolerazvan, @patelchandni,
Sorry to ping you directly ; do not hesitate to redirect me to proper instructions if I missed anything.

Could you guide me on how to have this pr be reviewed and integrated ?
I could take quite a long time to have all reviews, and as we have to integrate sprint number into the PR, I might have to merge/update quite often as the number of people involved is large.

Hello @Greybird I think in this instance Joaquin and Danny are part of the Web Apps task team and Chandni and I are part of the Functions team so just one approval is probably needed from each team.

@FinVamp1, you are right, sorry,
I have been confused by the "2 pending reviewers" mention, while the changes are actually approved. Thanks for pointing this!

I suppose there is nothing left for me to do currently, as checks now have to run, which I believe depends on some validation on Microsoft side ?
Do not hesitate to point to needed actions if I am wrong.

Thanks again for your guidance with the process !

Hello,

I updated sprint to 241.
I don't know how I can help further to have this PR merged.
